2027 EQA PROGRAMS
EQA 2027 - Serum biochemistry (CQH)
Expert Biologists - Program Coordinators:
Régine CARTIER, Christine LOMBARD, Estelle BUGNI, Laurent DESMURS and Patric DELISLE
EQA performed since 1973
Number of analytical sites registered in 2026: 699

1 – Program overview

This external quality assessment program assesses the accuracy of the most commonly performed biochemistry tests.

Statistical reports are sent with supporting comments from the expert clinical biologists / program coordinators.

Participating labs can choose to be assessed for all the analytes of this program, or simply a subset of analytes of interest.

2 – Assessment frequency

Number of surveys per year: 22
Number of control samples per survey: 1 or 2
Number of samples per year: 32

Among the 66 analytes included in this program, you can choose to have from 18 to 31 analytes assessed during each survey. Each analyte is assessed at least 4 times during the year for the least commonly used, and up to 16 times for the most commonly used.
